by:Geotec Engineering & Environmental Geophysics Ltd based inrishon letzion, ISRAEL
The measurement of electrical resistivity of the subsurface is one of the oldest geophysical methods (VES). It was developed during the late 1980s and the early 1990s as an electrical 2D and 3D imaging method for mapping the resistivity distribution in the subsurface CVES/ERT. Electrical resistivity is effective for shallow ...

Geophysical surveys are used to create maps of subsurface archaeological features. Features are the non-portable part of the archaeological record, whether standing structures or traces of human activities left in the soil. Geophysical instruments can detect buried features when their electrical or magnetic properties contrast measurably with their surroundings. ...
by:Park Seismic LLC based inShelton, CONNECTICUT (USA)
This type of survey is the most common and can usually achieve an investigation depth of 100 ft or less. Results can be 1-D, 2-D, or 3-D maps showing subsurface distribution of ground stiffness (quantitatively shear-wave velocity, Vs). These maps can show bedrock depth and topography, location of weak zones (e.g., sink-hole hazard or fracture ...

Most coal companies rely heavily on borehole data to evaluate their mine properties. However for the Underground Coal Gasification (UCG) and Coal Bed Methane (CBM) it is necessary to map the subsurface coal and to detect other spatial properties of the coal seam with a high degree of accuracy. Here the geophysical technology plays a vital role. The following are ...

Ground penetrating radar is the most effective non-intrusive method for detailed mapping, detection and imaging of shallow subsurface and for inspecting various structures' interiors. The radar enables to carry out measurements on almost any type of surface such as soil, rock, fresh water, air or concrete; it also allows performing measurements in boreholes, ...
by:Geotec Engineering & Environmental Geophysics Ltd based inrishon letzion, ISRAEL
A seismic survey is based on an energy source that excites seismic (elastic) waves in the subsurface. The seismic waves propagate in the subsurface and are reflected or refracted in the interfaces between mediums, having a different seismic velocity. The reflected and refracted waves are recorded on the surface by an array of receivers (geophones). The recorded travel times between the source and ...
